Attribute Value
Disconnect 60, 100, 260, 460, or
timer 600 milliseconds
Specify the duration of an Open Switch Interval (OSI) before a call on a supervised external line is
considered disconnected. This setting must match the setting for the line at the central office (CO).
You must enable disconnect supervision by changing the Line Trunk mode attribute. Under the
Telephony Services sub-heading, choose Lines and Line/trunk Data.
Clock Source Primary External
Secondary External
Internal
Designates whether the DTM/BRI acts as a primary or secondary timing component for an external
timing source or as the internal timing source.
Note: A BRI module can be programmed with primary/secondary clock source, however, it is
recommended that a BRI module always be set to Internal if a DTM exists on the system to be the
Primary External clock source.
Warning: Changing the clock source may disconnect calls.
If you change the clock source for your system, you may cause your system DTM interface(s) to reset,
resulting in dropped calls. Choose a suitable time to change the clock source and use the Page
feature to inform users of possible service disruptions.
Send Name Select or clear
Display
When you select this check box, the system sends a specified outgoing name display (OLI) from the
calling telephone.
Appears only for Protocols: SL-1, NI, DMS-100, DMS-250, or PRI QSIG.
Remote Select or clear
Capability MWI
Use this setting to indicate MWI compatibility on the specific loop(s) that you are using to connect to
the central voice mail system on a Meridian 1, that has the MWI package installed, with the RCAP
setting set to MWI.
Appears only for SL-1 protocol.
Host node M1, Embark, IDPX,
DSM
DPNSS cards connected to Embark switches have a different way of handling call diversion, therefore,
when you provision a DTM for DPNSS, you must indicate what type of switch the lines are connected
to.
When you select the Embark switch, calls are diverted using the Call Forwarding feature instead of
call diversion.
Local Number
Length
This number allows the system to determine how many digits to read on an incoming call to determine
that the call is meant for this system.
Maximum Default: 31
Transits
Indicate the maximum number of times that a call will be transferred within the SL-1 network before
the call is dropped. Protocol must be set to SL-1 to display this field.
